Stacked on #3051 (BlockInfo API refactor) — this branch is rebased onto refactor/block-info-api and adopts its vocabulary throughout (producers, NodeSpec.blockConfig, shared getInsertionPos); the parallel home-grown implementations are gone.

What this adds on top of #3051

Compartmentscontent: "inline" + children coexist, giving blocks a real rich-text title with a body of child blocks (fixes #2020, #2378). Title/body editing behaves as one unit: Enter splits into the body, Backspace merges back, Shift-Tab stops at the body edge.

renderFrame — second hook beside render that draws the box around content + children ({ dom, slot, update? }). Returning undefined declines the frame (plain nesting) — the toggle pattern. Pure containers can draw their box in renderFrame alone with in-place update; React renders pure-container frames live and installs compartment frames as static snapshots.

Derived repair — dissolve-vs-pad replaces configured strategies: below-min anywhere-containers dissolve into survivors (counted on content, not padded empties), containerOnly blocks pad, emptied container children are dropped while emptied regular blocks are kept.

Fail-fast validation — bad content+children combos, regular blocks in allow, require-cycles, and missing render/renderFrame all throw at spec-definition time.

Dropped as YAGNIdefault, whenEmptied, boundary: sealed, rootDOM, container runsBefore validation, removeEmptyChildren export.

Examples/docs09-container-block rewritten as a Panel (live frame + flavor switcher), new 13-callout-block headline demo (real inline title), container-blocks docs page updated.

Test plan

  • vp run lint (type-aware) — clean
  • core 907, tests/unit 947, react, multicolumn, all five exporters, xl-ai — green
  • e2e (browser suite) left for CI — Docker unavailable locally

📝 Walkthrough

Walkthrough

This change adds generic container-block support. It updates schemas, editing commands, rendering, React integration, side-menu behavior, exporters, multi-column blocks, documentation, examples, and test coverage.

Changes

Container block contracts and schema
BlockConfig now supports child rules and placement constraints. Shared helpers validate child configurations, identify container nodes, create child groups, and apply container attributes.

Editing and document behavior
Insertion, movement, nesting, merging, splitting, updating, repair, selection, and keyboard shortcuts now support nested and titled containers. Content carry-over and minimum-child repair are covered by new tests.

Rendering and React integration
Vanilla and React blocks support child references, optional frames, container attributes, frame node views, direct container resolution, and unwrapped container HTML output.

Exporters, examples, and documentation
DOCX, ODT, PDF, email, and Typst exporters pass children to container mappings. Multi-column blocks use generic container specs. New container and callout examples and documentation are included.

Priority: ➖ Normal — Schedule the unified container-block support because it spans editing, rendering, exporters, examples, and validation while addressing the medium-severity Enter-key behavior issue.

Estimated code review effort: 5 (Critical) | ~120 minutes

Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 17075

Container editing can still detach children or insert an invalid child, while some invalid schemas are not rejected cleanly. These issues should be resolved before merge.

commit: 4f3ade8

Build container ownership and editing on the BlockInfo helpers. Keep repair policy centralized, use the existing NodeView lifecycle for JS and React frames, and expose shared helpers through the core entrypoint.

Return the node unchanged when no descendant needs an id.

withGeneratedIds always rebuilds the whole subtree. In the common case the children were built by blockToNode, which already assigns an id to every block, so the rebuild mints nothing and only allocates.

The cost compounds with nesting. blockToNode recurses, so for a chain of d nested containers the innermost subtree is passed through withGeneratedIds once per enclosing container level. That makes container conversion O(d × n) instead of O(n).

Rebuild only the branches that actually change.

Destroy the editor in an afterEach hook.

editorWith mounts a real editor into the DOM. Every test destroys it as its last statement. If an assertion fails, destroy() never runs, so the mounted editor and its plugins leak into the following tests and can produce misleading cascading failures. Track the created editor and destroy it in afterEach.

Separate attribute synchronization from the content mount.

mountChildren is re-created on every render. React therefore calls the previous ref with null and the new ref with the element on each render. Two effects follow from that:

  1. applyContainerAttributes and the data-selected toggle only stay in sync because the ref identity is unstable. If a later change memoizes mountChildren, prop and selection updates stop landing on the author's root, and the test at ReactBlockSpec.container.browser.test.tsx lines 161-171 would be the only signal.
  2. TipTap's content host detaches and re-attaches on every container render, including renders caused by author-local state, which is DOM churn inside the editable region.

FrameNodeView already memoizes its mount callback on [mountContent]. Use the same shape here, and apply the attributes in an effect that depends on the block props, the id, and props.selected.

♻️ Proposed split of mounting and attribute sync
-              function mountChildren(element: HTMLElement | null) {
-                mountContent(element);

initialization into a suitable beforeEach or beforeAll hook, and destroy the
editor in the corresponding afterEach or afterAll hook. Ensure creation and
cleanup occur only as part of the test lifecycle rather than during collection,
while preserving the existing test behavior.

In `@packages/core/src/api/blockManipulation/containers/titledBlocks.test.ts`:
- Around line 20-24: Track the editor created by editorWith and destroy the
tracked instance in an afterEach hook, ensuring cleanup runs even when
assertions fail. Remove the individual per-test destroy() calls while preserving
each test’s existing behavior.

In `@packages/core/src/api/nodeConversions/blockToNode.ts`:
- Around line 348-362: Update withGeneratedIds to track whether any descendant
was changed and return the original node when neither it nor its descendants
needs a generated id. Rebuild only nodes whose own id or child list changed,
preserving existing attributes and marks for unchanged branches.

In `@packages/react/src/schema/ReactBlockSpec.tsx`:
- Around line 452-475: Memoize mountChildren with the same dependency shape as
FrameNodeView, depending on mountContent, so the TipTap content host is not
detached and reattached on every render. Move applyContainerAttributes and the
data-selected toggle into a useEffect that depends on block.props, block.id, and
props.selected, targeting the author root resolved from the mounted element. Add
useEffect to the React imports and preserve the existing wrapper validation.

882-884: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Move the titled-block Enter handler before the generic empty-block handler.

For an empty title with existing children, the generic handler runs first, moves the body into a sibling, and deletes the original child range. The titled-block handler preserves the body by inserting the new block inside it. Reorder these handlers so the titled-block handler handles this case first.

Handle mixed selections at a target-column edge.

If a drag contains all target-column children and blocks from another column, allTargetChildrenDragged is true and the handler returns without moving the extra blocks. Only use the no-op path when the dragged ID set exactly equals the target child-ID set. For a mixed selection that empties the target, calculate the insertion index from the original column order.

45-46: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject unknown block types in allow.

Line 45 skips validation when an allow entry is not in blockConfigs. For example, allow: ["typo"] passes validateChildrenConfigs instead of reporting an invalid children configuration. Reject entries that do not name a configured block before checking whether the block is a container. Add a regression test.

Proposed fix
-          allowed in blockConfigs &&
-          !isContainerConfig(blockConfigs[allowed])
+          !Object.prototype.hasOwnProperty.call(blockConfigs, allowed)
+        ) {
+          fail(type, `\`allow\` contains "${allowed}", which is not a configured block type.`);
+        }
+        if (!isContainerConfig(blockConfigs[allowed])) {

Assert that the existing child block IDs are retained.

The Enter path inserts a new paragraph into the existing body. The existing children remain addressable through their IDs. A replacement with identical text would pass the current assertion but break getBlock, updateBlock, or removeBlocks calls using the original IDs.

Proposed test assertion
       expect(shape(editor.document[1].children)).toBe(
         [
           'paragraph""',
           ...children.map((block) => `paragraph"${block.content}"`),
         ].join(", "),
       );
+      expect(editor.document[1].children.slice(1).map((block) => block.id)).toEqual(
+        children.map((block) => block.id),
+      );

Addressed the remaining review feedback in 4f3ade8. In addition to the inline-thread replies, the outside-diff validation finding is fixed: children.allow entries must name configured blocks, with regressions for unknown names, internal node-group names, and inherited object properties. The empty-title Enter test now also verifies existing child IDs are preserved. Validation: 34 core tests and 8 React frame tests passed; lint and commit checks passed. The shared alias-generator fix regenerates 104 configs, each with only the same three path corrections.
